Epiktistes

Epiktistes is my home in the Fediverse. It is an instance of Ktistec, a single-user ActivityPub server like Mastodon, but with fewer users and fewer commits. Here's my introduction (last updated early-2025).

I wrote a series of posts about optimizing the performance of the Ktistec server, its build time, and its executable size: part 1, part 2, part 3, part 4, and part 5.

Some things I regularly write about, organized by hashtag:

I also wrote some #pointfreeverse.

i took time off this summer to enjoy the analog world and play board games, but i did make some small progress in a few areas.

commits 31260ad through d6b35cb fix various bugs and performance problems and improve the user experience:

  • site setup is more user-friendly
  • social details (like and announce) are visible on posts
  • clicking anywhere on a post in a feed navigates to the post
  • links open in new tabs by default

there's a bunch of work under the hood, as well—mostly deferred refactoring and cleanup.

in parallel, i'm still working on metrics collection and charts. here's a teaser:

charts!

also demonstrated above is ishi—which tries to be a mathplotlib.pyplot like wrapper on top of gnuplot albeit written in crystal—and iterm2—which outputs charts to the console.
